Lever 45 is then pulled .in order to straighten outvthe toggle 42-43 which has a stop memberthereon1(not shown) to hold the' two links 42 and 43 of the toggle in the same straight line. The forward part of vthe vmachine is raised thereby and the Acutters 30, Scand 37 are raised off of the ground.v Theclutch 28 is then -thrown out, the machine is driven to the dump, and the lever l5 is disengaged fromV member Ii4 and thrown over to dumping position, as shown in Fig. 4. YAfter the load is dumped the lever is returned to its original position and zent-al. By this machine I am enabled to cutY 4sis the machine drivenback to the roadwhen lever 45 is thrownforwardly to engage the cutters, the clutch thrown in, and the `oper.

ation is repeated.V Y

The wheelsQO and 2l will be seen on differentflevels. providing such an arrangement the cutters are enabled to cut a substantially horizontal section of the road bed and thus in a measure form a completed roadbed after the desired amount of grading hasbeen performed. Of course'during the first twol or three cuts along the length of the road wheels 2O and 2l will be on the same level and first few cuts will not be horithe road toV within Vabout one foot of the bank wheneverfsuch a situation arises.

Having thus fully described my said invention, what lclaim as new and Vdesire to secure by Letters Patent, is
